Hi
i am experimenting with dialogflow, i can already turn on/off a light in a spefific room…
but seems for the 2 variables like on/off & room, you need to define them upfront
so for variable OnOff => values can be on / off
for for variable Room => values can be: kitchen, diner, garage…
you have to setup them upfront…
but how to make a variable, that can be complete random text? i want have a variable “text” , without even to know upfront, what that text can be …
as example, for shoppig list …
add “TEXT” to the shoplist … offcourse its not possible to define ALL items upfront 
thnx!
